Owners of a recreation area are filling a small pond with water. they are adding water at a rate of 35 liters per minute. there are 500liters in the pond to start. let w represent the amount of water in the pond (in liters), and let t represent the number of minutes that water has been added. write an equation relating w to t, and then graph your equation using the axes below.

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
